VENTILATOR.

Specification of Letters Patent.

Patented. March 5, 1907.

Application filed September 27,1906. Serial No- 3 364Q6t (all llfib lnizit 7)1/6I/ l/ concern:

Be it known that I, NILLIAM F. WARDEN, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to improvements in ventilators of the general type illustrated in United States Letters Patent No. 677,512, granted to Fred M. Harpham and Alfred Akers July 2, 1901; and the objectthereof is to provide a device .of the class namedhaving increased efficiency, wherein leakage isprevented by means directing its passage to the roof of the building, and further provided with means forsecurely retai device in a selected position.

A further object is to so construct the device as to permit as muchlight as possible to pass through it to the interior of the building and to secure the light-admitting substance by a noveland improved holdfast means.

With the foregoing and other objects in ning the closure view the invention consists in the novel construction, combination, and arrangementpf part-s constituting the invention to be hereinafter referred to,'and illustrated in the accompanying drawings, which forma part of this specification, in which is shown the preferred embodiment of the invention; but it is to be understood that changes, variations, and modifications can be resorted to which come within the scope of the claim hereunto appended.

In the drawings, in which similar reference-numerals indicate like parts in the different figures, Figure 1 is a side elevation of a ventilator of the type named with a portion thereof in section to better illustrate the mvention. Fig. 2 is an enlarged detail of meansfor securing the band by which thelight-admitting portion of the device is retained in position, and Fig. 3-is a detailof the mechanism bywhich the closure device of the ventilator is maintained a definite position.

In the drawings the reference-numeral 1 indicates the flue ot the ventilator, arranged to be located in the upper part of a building or other structure. The upper portion of the flue 1 is inclosed by a wind-shield 2, spaced apart therefrom and'supported by means to be hereinafter more fully described.

Surrounding the upper ortion of the flue 1 is a louver 3 above whic are a plurality of brackets 4, (only one of which is shown in struction and position thereof.) The windshield 2 is attached to these brackets 4. and

respect to the u per portion of the flue 1. Attached to the rackets 4 is a second louver 5, preferably arallel and in substantial alinement with t e louver 3 and spaced apart from the upper end of the flue 1, thereby constituting' an air-passage. Extending upwardly fromthe'louver 5 is a cylindrical portion 6.

In order to admit light to the structure ventilated by this device, there is placed across the opening inclosed by. the cylindrical portion 6 an approximately uninterrupted body of translucent material 8, retained in position by a contractible band or holdfast device 9 of substantially the configuration shown in Fig. 1-, having an upper convex contour. integral with a depending cylindrical portion 10.- The ends of this band 9 are detachably united together by providing one end thereof with an extended tongue 11, arranged to be passed'through a slot 12 in the ficiently to maintain the band in operative drical portion 6 and the translucent material. The space existing. between the member 8 and the band 9 is preferably filled with some packing, such as putty, (indicated' in the drawings bythe reference-numeral 13.) EX- perience has shown that even with the use of a packing between the band 9 and member 8 there stlll exists a liability of leakage.

leak through the joint between the band 9 and the translucent material 8 and which would otherwise drip into the structure vena trough 14, preferably conoid in form. At selected points through the cylindrical portion 6 are a number of perforations 15, by which any li uid which passes through, the joint formed etween the members 9 and 8 after passing downward over the inner surface of the cylindrical portion 6 may escape this type of ventilators, I preferably provide on the interior of the flue 1 a vertically-slidable sleeve 16v of a suitable size to be freely slidable therein, which when raised, as indicated in dotted lines in the drawings. closes Fig. 1, which serves to illustrate the conthereby is supported in proper position with opposite end of the band and be reflected sufposition with respect to the top of the cylin-' onto the top-of the louver 5. As is common in In order to convey any liquid which might I tilated by this device, I place on the interior of the cylindrical portion 6 of the ventilator mitted to pass freelyoutwardlythrough the space between the louvers 3 and 5, and-when the sleeve is raised into the position indicated in dotted lines in the drawings this'exit of air is prevented, as well as the ingress of foreign substances, such as'snow, rain, sleet, &c.

In order to retain the sleeve 16 at the point indicated by dotted lines in Fig. 1, whereby the exit of air is prevented, or atsome other selected point, I support, by means of the crossbars 17, a clip 20, into which the rope may be. placed by means of a slight manipulation by the operator and there held securely against movement, thus securely retainlng the sleev 16 in the desired position.

, I It will be stated'that the numberof louvers' employed in this device'may be increased without departing from the scope of this invention; but in eachcase the upper louver will constitute the roof of the structurejn the same manner that the-louver 5 does in the specific construction hereinbefoi'e given.

It will be obvious from the foregoing de-.

scription that substantially the entire area inclosed by ,the'flue l is supplied'by light admitted through the translucent material 8,

and'no lightobstructing devices worthy of notice are interposed toprevent its ingress, thus providing an unusually convenient deyvice in lighting apartments wherein ventila-l tors of this type are requiredand the ordinary expedients for supporting translucent v material commonly used asfl'a portion. of a ventilator are entirely eliminated. Another very desirable ieatu'reof this ventilator is the fact that..when shipping the same from the factory in'whicn it is produced to the buildinsz in which it is to be used the translucent material may be shipped separately in a suitable crate to prevent breakage thereof and then be placed in position on the ventilator by placing the band 9 in operativeengage- Inent therewith and closing the joint between the band 9 and the member 8 with ordinary packing material. It will be ob v'ious that when the ventilator, with its sheet of ltranslucent material fixedly secured thereon, is shipped-as a whole the danger of breakage of the translucent material andthe disadvantages of shipping the'same are greatly increased.

It will be further apparentthat in shipping large ventilators the desirability of being able to separately box or crate the sheet of translucent'material which is to be employed becomes a very important factor in supplyingthis type of device.

/vhatii claim, and desire to secure by'Letters Patent, is-,

The combination in a ventilator, of a flue, a roof therefor spaced apart therefrom and supported-thereby provided with an opening approximating" in size and area the opening in said flue, an upwardly-extending pcrfo-.

ratedwall on said roof surrounding said opening, a sheet of light-admitting substance mounted on and covering the space inclosedby said wall, means for securing said sheet of light-admitting substance in position, a flange positioned within said wall forming connection therewith a trough in open communication with the top of said roof through a perforation in said wall,- a-wind-shield for inclosing the upper-end of the flue and said roof, a-slidable'sleeve arranged-when in one position to close the space'exist-ing between the upper'end of. said flue and said roof thereby arresting the entrance of any foreign matters to said flue from the outside thereof, and meansfor moving said sleeve.

In testimony whereof I have hereunto set my hand in presence oftwo subscribing'wit nesses.

WILLIAM WARDEN.
